Reports

Cisco PVM provides a rich set of detailed, historical web-based reporting capabilities with comprehensive, pre-configured reports that provide a consistent and complete assessment of performance. You can run reports for specific resources configured by time period and scope, data view, and run time to give a snapshot of the status of network performance for historical and network management reporting purposes. These report parameters are easily managed from a single window.

The Cisco PVM Reports function allows you to generate information useful to various audiences, including IT staff, business managers, executives, and end users. The built-in report templates offer multiple views and drill-down capabilities displaying a variety of information with varying degrees of detail.

Under the Cisco PVM Reports tab, reports can be run immediately or scheduled to run at a later time, and can be viewed, printed, and saved as PDF, Microsoft Excel, and Rich Text Format files.

Note Reports run under the Cisco PVM Reports tab are archived; those run using the Monitor function are not.

Drill-Down Capabilities

Cisco PVM reports display hyperlinks for linking one report to another. For example, from the Applications Report that displays a list of protocols in table rows, you can click on a Protocol hyperlink to access the Application Details report for that protocol. This section describes drill-down rules and design.

General Rules

Cisco PVM reports adhere to the following rules for hyperlink access among reports:

•Host IP addresses—Each time you see a Host IP address, you can drill down to the host details.

•Application—Each application allows you to drill down to the application details.

•NAM name—Each time you see a NAM name, you can click on the name to open a new window for the individual NAM GUI and automatically sign in the individual.

•Real-time charting drill-down—Each time you see an "R" hyperlink, you can click on the "R" to open a new window to monitor this report row details graphed in real-time. Drill-down capability is available on both Data Source view and All NAM view, for all tabular reports.

•Trend Reports drill-down—Each time you see a "T" hyperlink, the you can click on the "T" to drill down to this report row details graphed against the selected time period. This drill-down capability is available on both Data Source view and All NAM view, for all tabular reports.

Table 4-10 shows the Cisco PVM reports and the reports you can access through the available drill-down hyperlinks.

Drill-Down Link Formats

Figure 4-14 depicts the drill-down from a Hosts report to the Host Details report.

Figure 4-14 Sample Drill-Down Format - Hosts to Host Details

The host IP address for which the user wants to see details appears as a red hyperlink in the report shown on the left, and its respective Host Details report, shown on the right, opens when that hyperlink is clicked. In the Cisco PVM GUI, the second report replaces the initial report in the report display pane. You can click Back in the report header to see the initial report.

Using Report Drill-Down Links

Note The drill-down links are available in tabular reports only. Cisco PVM tabular reports include those run for cumulative and current rates; TopN reports do not display the drill-down links.

Step 1 Open a tabular report by running a new report or opening an archived report.

Step 2 In the table, find the linked resource about which you want more information, such as the Host ID or Protocol.

Tip You can use the sorting arrows in the column header to re-sort the resource or performance information, or use the pagination links in the report header to view different pages of the report.

Step 3 Click the desired resource name or application protocol hyperlink.

The drill-down report opens and replaces the display of the original report.

Step 4 Click additional resource name or application protocol hyperlinks available in the first drill-down report to display additional reports containing details for the desired resource or application.

Opening the NAM Traffic Analyzer

You can link directly to the Cisco NAM Traffic Analyzer for NAM configuration options from Cisco PVM reports. The traffic analyzer opens in a new window.

Note The traffic analyzer opens directly to a specific NAM only if that NAM has been set up in Cisco PVM with the correct user ID and password (see Setup > NAM in the Cisco PVM GUI) or if the current Cisco PVM user credentials match the NAM credentials. If the traffic analyzer does not open for the desired NAM, log in to the NAM using the traffic analyzer's login window, or contact the Cisco PVM administrator to obtain traffic analyzer login information.

Step 1 Open a report by running a new report or opening an archived report.

Step 2 Click the "NAM (Type)" hyperlink at the top of the report display window. The NAM Traffic Analyzer opens in a new browser window, signed on automatically to the correct NAM if that NAM logon information has been set up in Cisco PVM or if your user credentials allow you to access the NAM.

Figure 4-15 shows the NAM Traffic Analyzer window opened just beneath the "NAM (Type)" hyperlink.

Figure 4-15 NAM Traffic Analyzer Window

Step 3 Review or change NAM or switch/router parameters in the traffic analyzer window.

Note Changes you make using the traffic analyzer affect future data aggregation and reports only.

Step 4 Close the NAM Traffic Analyzer by clicking the close button in the upper right corner of the window.

Real-Time Charts

Cisco PVM provides access to real-time data through links available in tabular reports. Reports contain a link in each table row that opens a chart pop-up for the corresponding report element, such as a host or protocol.

The Real-Time Chart pop-up allows you to troubleshoot a specific data source by displaying a continuously refreshed plot of its current performance. Monitoring begins as soon as the window opens. The chart will automatically refresh every 30 seconds and additional data points will be plotted. At any time, you can change the selected variable and click Submit to restart monitoring.

Note If you are viewing an archived report, it is possible that you won't be able to view real-time data if the old data has been overwritten in the Cisco database. This can happen if you have a busy NAM generating large amounts of certain data types. In this case, clicking the "R" link in the report opens the Real-Time Chart window with a message indicating that no data is available for the specified parameters.

This section contains the following topics:

•Variables Available for Real-Time Monitoring

•Displaying a Real-Time Chart

Variables Available for Real-Time Monitoring

Variables are displayed for individual statistics as rates in units per second (such as PACKETS/SEC). This rate reflects the change in the selected variable value over time.

Trend Reports

Cisco PVM provides dynamic performance reporting capability within the Reports GUI by displaying a link to a Trend Report on each report pane. The report displays raw data for the selected network component (such as protocol, host, or interface) with a superimposed line showing the data trend over time, offering a magnified view of the data flow for analysis of abnormal or problematic patterns. To see different statistics for the same report displayed as a Trend report, simply click a different metric within the report display (such as PACKETS or BYTES) and the chart automatically refreshes.

This section contains the following topics:

•Trend Statistics

•Displaying a Trend Report

Trend Statistics

Trend reports are available from tabular reports (those showing Current Rates or Cumulative Data) for the following statistics:

•Applications

•Interface

•Ethernet Traffic

•Ethernet Errors

•Conversations

•DSCP

•DSCP Application

•DSCP Host

•Hosts (IP)

•Hosts (MAC)

•VLAN ID and

•VLAN Priority.

The various metrics for each statistics are viewable through links directly in the Trend Report.

Drilling down from a tabular to a Trend Report depends on which Report View is currently displayed. The drill-down rules are summarized in Table 4-13.
